AVR32_CTXT_SESSION | AVR32_SESS_RUN_LED | Sets the RUN indicator 0x00 = stopped 0x01 = running | W | 1 byte
AVR32_CTXT_PHYSICAL | AVR32_PHY_PHYSICAL | Selects the physical interface 0x00 = None 0x04 = JTAG 0x07 = aWire | RW | 1 byte
AVR32_PHY_JTAG_CLOCK | JTAG clock frequency [kHz] | RW | 2 bytes
AVR32_PHY_AW_MAXBAUD | Maximum aWire baud [kbps] Baud rate is configured automatically, but a ceiling value can be set. | RW | 2 bytes
AVR32_PHY_DAISY | Devices before << 24 Devices after << 16 IR-bits before << 8 IR-bits after << 0 Note that daisy chain settings must be written before activating the JTAG physical. | RW | 4 bytes
